728741 divided by 9 
The aim is to understand the frequency of 9 in 728741.

Going ahead to step 1:
9 can be fit into 7 0 times, resulting in a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 9

Moving on to step 2:
When dividing 72 by 9, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 8.0
Subtract 72 from 72 to get 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 9

Step 3:
9 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 80.0
If we subtract 0 from 8, we get 8.
Include the next digit (7) from the dividend after 8, then repeat: 87 / 9

On to step 4:
87 divided by 9 is 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 809.0
If we take 81 away from 87, we end up with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 9

Let's proceed to step 5:
When dividing 64 by 9, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 8097.0
The remainder is 1 after subtracting 63 from 64.
Grab the next digit (1) from the dividend, add it to 1, then carry on: 11 / 9

Moving on to step 6:
11 divided by 9 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 80971.0
If we take 9 away from 11, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 80971.2
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 80971.22
The remainder is 2 after subtracting 18 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 80971.22 with a remaining 0.002.
